Suggestopedia is a teaching method developed in the 1970s by Bulgarian psychotherapist Georgi Lozanov. It aims to optimize learning through creating a relaxed environment where students feel confident and motivated. Key aspects include playing Baroque music, arranging furniture in a semicircle facing the board, using posters to aid peripheral learning, and limiting homework to rereading material. The goal is to utilize both short and long-term memory through lessons with emotional meaning that promote assimilation before analysis.
